Verification Check these files and commands for similar content:
-- /etc/resolv.conf --
domain mycorp.com
nameserver 15.0.10.123
search mycorp.com
-- /etc/hosts --
aa.a.aa.aaa hostname.domain.name hostname
127.0.0.1 localhost loopback

default 15.1.48.1 UG 0 0 lan0 1500
Fix • Make sure that the /etc/hosts file does not contain a line such as:
127.0.0.1 node_name localhost.localdomain localhost
with both the node_name and the loopback IP address set to 127.0.0.1. This situation
would prevent successful task execution on the managed node.
• On HP-UX, execute set_parms initial, and perform any additional manual
modifications of the files that may be required. On Linux, perform any manual
modifications of the files that may be required.
